Abstract
A rapid new procedure is described for getting the total no. of fringes J from Gouy fringe pattern data. This PQ method is exact and the results excellent (within 0.01 - 0.03 fringe) for ideal systems (Ωj = 0 for all j, Q0 = 0). Such systems include most binaries; for these, the diffusion coeff. is either const. or a polynomial function of concn. with small concn. differences. For multicomponent systems and some binaries, Q0 can be significantly different from 0. In these cases, the PQ method unambiguously gives the integer no. of fringes. If in addn. Q0/Q1 is larger than 2.0, then J obtained from a second extrapolation procedure is also good.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
